1. IN A ROTARY RAILROAD CAR DUMPER HAVING A PLURALITY OF CLAMPS MOVABLY MOUNTED ON THE DUMPER FRAME FOR ENGAGING AND HOLDING A RAILROAD CAR ON A TRACKWAY OF THE DUMPER AS THE DUMPER ROTATES, THE IMPROVEMENT WHICH COMPRISES MEANS FOR MOVING EACH CLAMP INTO AND OUT OF ENGAGEMENT WITH THE RAILROAD CAR, COMPRISING IN COMBINATION: (A) A LINKAGE SYSTEM ASSOCIATED WITH EACH CLAMP; (B) A COUNTERWEIGHTED LEVER ARM COUPLED TO EACH LINKAGE SYSTEM AND PIVOTALLY MOUNTED ON THE DUMPER FRAME FOR ACTIVATING THE LINKAGE SYSTEMS; (C) A CAM FIXEDLY MOUNTED ADJACENT THE ROTATING DUMPER FOR ENGAGING EACH COUNTERWEIGHTED LEVER ARM AS THE DUMPER MOVES TO A POINT OF 0 ROTATION WHERE A CAR POSITIONED WITHIN THE DUMPER IS IN A NORMALLY
